Yield:520-33-2 87%
Reaction Conditions:
with sulfuric acid in ethanol; for 8 h;Reflux;
Steps:
1 Synthesis of compound 1:
Weigh hesperidin (72g, about 0.12mol) into a 1000mL round-bottomed flask, add 720mL of 10% concentrated sulfuric acid ethanol solution, place in an oil bath and stir well, and heat to reflux. After 8 hours of reaction, after cooling, pour Into ice water, a solid precipitated, left to stand, suction filtered, and dried.The crude product was heated and dissolved with ethanol, and the activated carbon was decolorized and filtered.The filtrate was recovered under reduced pressure. The solid was recrystallized from ethanol and dichloromethane.A white solid was precipitated, suction filtered, and dried to obtain a hesperetin powder (31.5 g) in a yield of 87%.
